"Easy" difficulty is actually not that easy
Submitted by Gautier Pelloux-Prayer
It MAY be related to bug #759039 (lack of contrast / hard to play), but the same casual user reported me that he had hard time finishing a easy puzzle in gnome-sudoku (15 minutes).
He also gaves up all his other parties after 20 minutes. He regurlarly does newspapers' sudokus and finishes them so maybe difficulty in gnome-sudoku starts too high?
